Abstract

The invention relates to a bactericidal composition with synergistic effect. The bactericidal composition contains active ingredients A and B, wherein A is captan and B is selected from isoprothiolane, fenoxanil and iprobenfos. A weight percentage ratio of the active ingredient A to the active ingredient B is (2-78 percent):(2-78 percent); and the active ingredients are added with aids and excipients to be prepared into wettable powder, water dispersible granules, a suspending agent or suspension emulsion, and the bactericidal composition is mainly used for controlling rice blast, rice false smut, rice sheath blight and the like, and has obvious synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing captan to rice diseases. technical background [0002] Captan (captan), molecular formula: C 9 h 8 C 13 NO 2 S, chemical name: 3a,4,7,7a-tetrahydro-2-(trichloromethylthio)-1Hisoindole-1,3-(2H)-dione. Captan is an organosulfur fungicide with both protective and therapeutic effects. Its mechanism of action is mainly to affect the metabolism of pyruvate in pathogens, and it has obvious inhibitory effect on various enzymes. It can also reduce the content of adenosine triphosphate in pathogens to prevent the release of conidia of pathogens. [0003] Long-term use of a single dose of captan can easily lead to drug resistance in diseases, leading to problems such as increased dosage, reduced control effect, and shortened duration, which is not conducive to sustainable development of the environment. The compounding of active ...
